The compact and lightweight navy 8x21 U-Series UP Binocular combines aspherical optical elements and BAK4 Porro prisms to deliver edge-to-edge image sharpness with a 50° angle of view. The optical elements are also fully multicoated to provide a high transmission of light. With an 8x magnification and 21mm objectives, you obtain a notable magnification, insignificant image jitter due to unsteady hands, and a compact form factor. You can easily spot your targets with a wide 6.2° angular field of view and quickly bring them into focus with a center focus wheel. In addition to observing distant scenes, birds and game, the minimum focus of 9.2' allows you to study in detail close objects like animal footprints, marks or landscape features. The binocular also features a 2.6mm exit pupil, a 13mm eye relief, an interpupillary and a diopter adjustments.

The binocular is very compact, lightweight, and features a single piece frame that houses objectives, which allows for a synchronized interpupillary adjustment. To accommodate glass wearers, the binocular offers sliding rubber eyecups. Also included are a carrying case, a neck strap, and eyepiece covers.

Great value for a one-time event! Perfect for graduation.
Color: Black, Size: Large, Color: Black, Size: Large
I bought this suit for my son's graduation, and it was exactly what we needed. Since he will probably only wear it once, I didn't want to spend a fortune at a high-end department store. For the price, the quality is surprisingly good; it looked sharp and he received a lot of compliments during the ceremony. We ordered a size Large (L) based on their sizing chart, and it was true to size and fit him perfectly. The fabric is lightweight but doesn't look cheap at all, making this a fantastic, excellent cost-benefit choice if you are looking for an option for a one-time event. Highly recommended!

Great for the price.
Color: Black, Size: Large, Color: Black, Size: Large
I’m 220lbs 6’1 athletic build. Arms/back couldn’t fit inside the jacket. Pants and vest fit fine though. I honestly should get stuff tailored considering my body competition. Good quality for the price worked for me.

XL sized suit review
Color: Light Blue, Size: X-Large
I ordered XL for my husband who is 6'1" and weighs 200 lbs. The pants' length was too long and we had to cut off two inches and get them hemmed. Jacket could be a little bigger in the mid section and shoulders but vest fit well. Could do without the fake handkerchief in the suit jacket pocket. Still liked the style and the color of the light blue suit.

Perfect for teens
Color: Black, Size: XX-Large
Great suit! Great quality for the price. Very impressed. Bought for my teens. Didn't want to spend a lot on something they won't wear more than a couple times before they grow again. This suit is great. A tad long in the arms and legs. But overall, its perfect. Fitting suit, but got a size larger for their comfort. Surprised at the quality, my mom was impressed and she knows suits.
